Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically to a corrosion-resistant and wear-resistant fabric adhesive tape that can be used in automotive engine compartments. Background Technology

[0002] The engine compartment is the hottest area in a car and comes into contact with various fluids such as transmission fluid and battery fluid, as well as various chemical reagents. Battery fluid, in particular, is composed of strong sulfuric acid, which is highly corrosive. Furthermore, the engine compartment experiences significant vibration, necessitating a covering to protect the wiring harnesses in this area and improve their overall wear resistance and corrosion resistance. This reduces friction and corrosion damage to the wiring harnesses while maintaining their flexibility. Existing conventional wiring harness tapes are generally unable to simultaneously meet these performance requirements. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a wear-resistant and corrosion-resistant fabric tape with high corrosion resistance and wear resistance, which can be used in automotive engine compartments.

[0004] To achieve the above objectives, this utility model is specifically implemented through the following technical solution:

[0005] A corrosion-resistant and wear-resistant fabric tape comprises, from the outermost layer to the innermost layer, an anti-corrosion coating, a base fabric, and a high-temperature resistant acrylic adhesive layer. The anti-corrosion coating is formed by spraying with a heat-treated silicone-based pressure-sensitive adhesive. The base fabric has a plain weave structure, with 100% carbon fiber weft yarns and high-strength PET filament warp yarns. The base fabric has a basis weight of 130–160 g / m². 2 The thickness is 0.25±0.05mm; the high-temperature resistant acrylic adhesive layer is coated with acrylic light-curing adhesive.

[0006] Furthermore, the adhesive weight of the anti-corrosion coating is 30-50 g / m³. 2 .

[0007] Furthermore, the weft strength of the fabric base layer is 3-5 CN / dtex, and the linear density is 180D; the tensile strength of its warp is 7-8 CN / dtex, and the linear density is 150D.

[0008] Furthermore, the coating weight of the high-temperature resistant acrylic adhesive layer is 100-150 g / m². 2 Its heat resistance temperature is above 150℃, and its peel strength is at least 2.5CN / cm.

[0009] This utility model's anti-corrosion, flame-retardant, and wear-resistant fabric tape uses a high-quality anti-corrosion and temperature-resistant coating and a plain weave structure substrate, with a high-performance acrylic adhesive as the glue layer. The product has a simple structure, high production efficiency, and high anti-corrosion and wear-resistant properties. After 1000 hours of battery liquid resistance, the tape remains soft and does not crack. It can be used in the engine compartment of automobiles to improve the wear resistance of wiring harnesses and reduce the impact of harsh chemical reagents on wiring harnesses under high external temperatures. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0011] In the diagram, 1-anti-corrosion coating; 2-fabric base layer; 3-high temperature resistant acrylic adhesive layer. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, this utility model discloses an anti-corrosion and wear-resistant fabric tape, comprising, from the outermost layer to the innermost layer, an anti-corrosion coating 1, a fabric base layer 2, and a high-temperature resistant acrylic adhesive layer 3. The anti-corrosion coating 1 is formed by spraying a heat-treated silicone-based pressure-sensitive adhesive. The heat-treated silicone-based pressure-sensitive adhesive is a silicone-based pressure-sensitive adhesive that has been heat-treated at 150–200°C for 5–10 minutes to ensure its excellent anti-corrosion performance. The fully cured heat-treated silicone-based pressure-sensitive adhesive has good resistance to chemicals and can withstand 50% sulfuric acid and nitric acid for more than 100 hours at room temperature. Simultaneously, the highly coiled molecular weight of the siloxane in the heat-treated silicone-based pressure-sensitive adhesive, with its helical structure, results in a low surface energy, preventing the substrate from adsorbing sulfuric acid even when immersed in sulfuric acid liquid. Preferably, the coating weight is 30–50 g / m². 2 .

[0014] The base fabric 2 has a plain weave structure, with 100% carbon fiber weft yarns and high-strength PET filaments warp yarns. The base fabric has a basis weight of 130–160 g / m². 2 The thickness is 0.25±0.05mm, the weft strength is 3-5CN / dtex, preferably 3.5CN / dtex, and the linear density is 180D; the warp tensile strength is 7-8CN / dtex, preferably 7.8CN / dtex, and the linear density is 150D. The base layer 2 maintains high flexibility and abrasion resistance even after being exposed to battery liquid, with an abrasion resistance of 1000-4999 cycles.

[0015] The high-temperature resistant acrylic adhesive layer 3 is coated with an acrylic photocurable adhesive, and the acrylic adhesive is cross-linked by UV radiation curing. The molecular chain of the high-temperature resistant acrylic adhesive layer 3 itself contains a UV irradiation initiator and 10% to 20% high molecular weight unsaturated synthetic rubber. Low-wavelength irradiation is used in production, eliminating the need for nitrogen protection and preventing small molecule degradation. It can achieve long-term heat resistance of over 150°C and also possesses pressure sensitivity. Preferably, the coating weight is 100 to 150 g / m². 2 The curing rate is 70% to 85%; its heat resistance temperature is above 150℃; and its peel strength is at least 2.5 CN / cm.

[0016] like Figure 1 As shown, the tape of this utility model is stored in rolls. During use, the anti-corrosion coating 1 on the tape body provides anti-corrosion performance to reduce the chemical corrosion of the internal wire harness; the cloth base layer 2 provides wear resistance and reduces the decrease in tensile strength caused by corrosion; the high-temperature resistant acrylic adhesive layer 3 provides sufficient adhesion to the cloth base layer 2. The good adhesion and excellent chemical resistance can tightly adhere the tape to the wire harness, and provide sufficient adhesion in high-temperature environments to prevent peeling and delamination.

[0017] The specific embodiments described herein are merely illustrative of the invention and are not intended to limit it. Those skilled in the art can make modifications to these embodiments without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of this invention.
